IMPROVEMENT IN WIRE BROILERS AND TOASTERS.

The Schedule referred. to in these Letters Patent and making part of-thesame.

Know all men by these presents.-

" wire frame; and

Figure 3 represents a transverse section of the wire of which the mainor skeleton frame is made.

To enable those skilled in the art to which my invention belongs tomakeand use the same, I will describe it more in detail.

The nature of my invention consists- First, in constructing the main orskeleton frames of wire broilers and toasters of peculiarly-shaped wire,as hereafter explained.

Second, in the combination, with the main frame, of grooves or notches,for receiving the ends of the filling-bars, as hereafter explained.

In the drawings, the parts marked A A represent the top and bottom mainframes, to which are attached the filling-bars B B.

The wire of which the main frames A A are made is drawn or rolled,previous to'being bent into form, whereby it is compressed in suchamanner as to produce a V'-shaped ridge, (1, at one side, as shown infig. 3 of the drawings, and through which V shaped ridge grooves I) arecut or formed, as indicated in fig. 2 of the drawings.

The wires are then bent into squares, as shown, and the ends joined atone of the corners, by bending one end around the other, as shown atO.

The notches or grooves 12 are formed at two sides of the square or mainframe, transversely across the ridge a, in which the ends of the bars Bare placed, and where they are secured by bending them around the wiresof the frames A A, as shown in the drawings. g

Two of the bars D, on each of the frames, are pro jcctcd beyond theflame-forming loops E, which serve for a handle, and upon one of theloops is arranged the slide F, by means of which the two parts are heldtogether when in use.

, The parts are hinged together at the back by links G, in the usualmanner.

By making the frames A Aof V-shaped wire, they are much firmer than theywould be if formed of round wire.

By means of the grooves or notches b, the bars are always retainedsecurely in place.

In using wire which has the ridge or projection a, thereis much less ofthe metal cut away to form the grooves 1) than there would be if thewire were round,

' consequently the frames are much stronger, and more durable, and .arenot liable to get out of order by the bars becoming loose, while at thesame time the process of manufacture is greatly facilitated andcheapened.

Having described my improvcdtwire broiler and toaster,

, What Iclaim therein as new and of my invention,

and desire to secure by Letters Patent, is

1. The main or skeleton frame, made of V-shaped wire, as and for thepurposes set fortlu 2. The combination, with the main frame, made ofgrooved V-shaped wire, as shown, of the filling-bars B, substantially asand for the purposes set forth.
